Since we have experts of every possible description here, I wonder if someone can positively identify this object for me.
It's a stone (something), over seven inches long, that has obviously been fashioned by someone into its present shape.
When DW was a girl, she walked through the fields after her father had plowed each year and picked up arrowheads and other assorted stone artifacts. They were very numerous in the area, and she has quite a collection. This particular object has always intrigued me, and our best guess is that it was the head of a war club that could be fastened onto a handle. But the fact that one side is flattened has always bothered me and I wonder if it may have had another use.
If it helps any, this was found in southwestern Ohio.
